. nmm cmmrn DEVICE.,

2 t all wwm- 2t may concem Be ,it known that I, GEORGE EDWIX JONES, a citizen of the United States, residing at Chicago, in the county of Cook and State of I]linois, have invented certain .new and uselh Improvements in Refrigeracing Devices, 0f Which the following is a specification.

M intention relates to' refrigerating or chilling devices and lias particular reference to. a derme adapted for refngeratwnby evaporation. It 13 a well known sc1ent1fic fact that heat un1ts 'may be subtracted from a bodv bV evaporation of a liquid and that the eirterit of subtraction of such nuits is proportionate to the speed ofevaporation. The heat w'hich thus disappears by' virtue of the passage of the liquid mto a gascons condition is called the latent heat of evaporizaiion. By the use of an exceedingl; volatile liquid an extreme cold may be produced. However, the pressent invention relates to a device for use withordinary water by reason of which articles may be chilled and retained in such condition indefinitely, the only requirement being that the water is kept'supplied to the walls of the container. A

I am aware that 'it is not broadh new to prov1de a desice similar to that herein shown and described and having many of the properties thereof. However, in the devices heretofore suggested, 'it has been necessary to s'upply the liquid to the walls of the container by immersing the container as a whole,or in some other eqall inconvenient manner, Furthermore, the water thus ap-= plied would very shortl v evaporate making necessary further applications thereto. .I have tlierefore devised a refrigerating container s0 arranged that a sufficient amount of water may be applied to maintain the walls in saturate condition for a much longer time thari has -heretofore been possible.

'My invention will be more readily understoodby reference to the accompanying draivings, wherein,

Figure 1 is a s1de elevat1on of a contamer such as contemplated by me, and Fig. 2 15 a in Fig. 1.

comprises a lower or base portionlO, having Referring more particularly to the draW- ings'it Will be seen that my container 1s pref-' erably oval in cross-sect1 onal ou thne and Specification of Iietters Patent, PatentedFebg13, 1912. Application fi1ed October 12, 1911. Seri'al No. 654,290,

tainermay be rested. The 1'1pper edge of this half terininates in a trough' 12 and an upstanding pripheral rib 13. In order to direct the liquid .to the inner.a'nd outer portions of the wall and thoroughly the same, I=provide Within the trough 12, a plurality of staggered depressins 14, 15. 'It will be seen that the depressions 15 direct the -water to the outside portion of the wallS I cohtemand the holeS 14 to the 'inside. plate providing: 'ajlarge number -of these holes around the ;upper edge of the lower container and by this means provide a re ceptacle for liquid whi'ch Will not be taken' Vent direct evaporation .of the liquid, be-

fore it can be taken up -by the matrial forming the wall.

It will be unclerstood that the container described is preferably formed of plaster of Paris or some matenal haiirig sucl i propert1es, that is, the propertyof absorbing'a large quantity-of water and which Will not take up od0rs from.the articles carned in Therfore by distribut,

the container. The uppcr half 16 of the container lias at its lower extremity an inwardly facing groom 17, adapted to'fit over the flahge 13, and provide against the shifting of the top. In order to permit of the easy handling of the device and also to provide a .furtherwater reservoir, I fui*nish the upper extremity of the container with a flange 18, forniing a trough 19, having similar holes 20, 21, the holes.20 directing water to the outside portions of the'walls and the holes 21 to the inside. -In -order to pre vent the formingof a vacuum withinthe container and also to permit the escape of heat, I provide perforations 22, through the walls of the upper half.

In operatiOn, the articles to. be chilled are placed Within the container, the cover or upper 'half 16 aliplied, then a quantity o f water is poured into;-the upper and lower troughs and allowed to soak into the Walls.

TAS soon as th -Walls becoihe' saturated, wa-

' ter Wlll remain in thetroughs and perfora-' tions,ready to -percoJate intothe walls as
